although the author claims it’s imcomplete and a work in progress there’s a stunningly large amount of information in the sherlockian atlas. (it also hasn’t been updated for over four years so i’d guess we can presume it’s as complete as it will get.) every geographical place, both real and fictional, that features in the sherlock holmes story is here, with references to where they appear, from the obvious places like 221b baker street and the reichenbach falls to, well, places on every continent and throughout london.
